To all whomz't may concern:

Be it known that I, J. S'inm, residing at Chicago, county of Cook, Stateof Illinois, and being a citizen or the" United States, have. inventedcertain new and useful Iinpiovements in Means of Securing a 1 WoodenLining to a (tor'rugat ed Vi a-ll, of which the following is afull,clear, and exact description, such as wili en'ablefiothers skilled intheartto which it appertains to make and to" use the same, referencebeing had to the accompanying drawings; which illustrate" the preferredit of 'theginv'ention, though it is to be understood thatth'e inventionis not limited toth'e es'ra'crdetails of construction shown' anddescribed, asit is obvious that various modifications thereof within thescope of the claims will occur to persons skilled in the art.

Corrugated metallic end walls of variousv types are in general use whichcomprise metallic plates having corrugations of different configurationsformed therein to strengthen and stiffen them. Such ends are made of aplurality of plates with the meeting edges positioned horizontally orvertically and with the corrugations positioned horizontally orvertically. However, the number of plates or position of thecorrugations is immaterial to my invention.

It is customary to line such corrugated ends with wooden boards toprevent the grain from sweating and mildewing; secondly, to providemeans for blocking the lading; and thirdly, to prevent grain leaks. Itis essential that this lining be secured by means which would not permitmoisture to enter the car. Nailing strips have been inserted in thecorrugations and held thereto by bolts which project through thecorrugated end, but experience has shown that moisture and dampnessfollow this bolt.

It is customary to run the lining boards perpendicularto the directionof the corrugation and it is preferable to allow the run-' ning boardsto bear against the apices of adjacent corrugations so that the thrustof the shifting lading will be carried directly through the lining boardto the corrugation.

This lining must be fastened securely and rigidly to the end wallbecause the anchoring of the lading and the racking of the car have atendency to loosen it.

One of the objects of the invention is to securely and rigidly fasten awooden lining Figsi 5,6 and? 7- show the to a corrugated metallic wallof a railway boxcar.- I Y Inthedrawing's: I

fronr tlie'insideof the car with the lining and naii'removed; v 4 Vholder in detail.

In the drawings 1 is a corrugated metallic wall having inwardlyprojecting apices 2, outwardly projecting apices 3 and lining 4. Thefastener 5 is held to the corrugated wall 1 by rivets 6 or otherconvenient means. The fastener 5 is formed so as to provide adjacentportions 7-8 with the inclined portions 910 and curved portion 11. Thisfastener 5 may be of any desired length. The lining is held against theadjacent apices 22 while the nail 12 is driven in place. This nail 12 isguided by surfaces 9 and 10 into the space between portions 7-8 and uponcoming in contact with portion 11 the nail is deflected or clinched, asshown at 13, so that it rigidly secures the lining in place.

In the modified form shown in Figs. 3 to 7 inclusive the fastener issecured to the corrugated wall 1 by rivets 21 or any other convenientmeans. The holder 22 is secured to fastener 20 by bolts 23 (or any otherconvenientmeans) through holes 24. The holder 22 is provided withinclined or guiding surfaces 25 so that as the nail is driven in placeit is guided by these inclined surfaces 25 and portion 26 of thefastener so that the nail comes in contact with and is deflected byportion 27 of the fastener, thereby forming a hook connection with thevholder 22. The fastener 20 or holder 22 have inclined surfaces 29.These ribs pre vent the nail from bending sidewise.

My devlce is positioned within the planes bounding the inwardly andoutwardly projecting corrugation so that it permits the lining 4 to bearagainst the adjacent apices 2 of the corrugations and furthermore doesnot necessitate any increase in the length of the car. However, myinvention is not limited to placing these fasteners within thecorrugation.

These fasteners 5 and 20 are preferably applied to the corrugated wallbefore it is installed on the car.

I claim:

1. In combination with a wall element for a railway car having aplurality of corrugations formed therein, a fastener secured to saidwall, a lining, a nail securing said lining to the fastener, saidfastener comprising means to guide and deflect the nail as it is drivenbetween adjacent portions of the fastener whereby said nail is retainedbetween said portions.

2. In combination with a wall element for a railway car having aplurality of corrugations formed therein, a fastener secured to saidwall within one of said corrugations, a lining touching the apices ofadjacent corrugations, a nail securing said lining to the fastener, saidfastener comprising means to guide and deflect the nail as it is drivenbetween adjacent portions of the fastener whereby said nail is retainedbetween said portions.

3. In combination with a wall element for a railway car having aplurality of corrugations formed therein, a fastener secured to saidwall, a holder secured to said fastener a lining, a nail securing saidlining to the fastener and holder, said fastener comprising means toguide and deflect the nail as it is driven between the holder and thefastener whereby the nail is retained between said holder and fastener.

4. In combination with a wall element for a railway car having aplurality of corrugations formed therein, a fastener secured to saidwall within one of said corrugations, a holder secured to said fastener,a lining touching the apices of adjacent corrugations, a nail securingsaid lining to the fastener and holder, said fastener comprising meansto guide and deflect the nail as it is driven between the holder and thefastener whereby the nail is retained between said holder and fastener.
